The reliability of the software includes correctness and what

1. robustness. According to the relevant information of the query, the meaning of software system reliability includes both correctness and robustness. In other words, reliability means that the system can work correctly under normal circumstances; it can be handled appropriately in abnormal situations without causing serious losses.

2. Software reliability is the ability of software products to complete specified functions under specified conditions and within specified time intervals.

3. Reliability compliance: refers to the ability of software products to adhere to standards, agreements or regulations related to reliability and similar provisions.Ease of use: refers to the ability of software products to be understood, learned, used and attracted by users when used under specified conditions.

4. Reliability refers to the ability of the software system to operate normally and provide correct results in a specific environment. Reliability includes the stability, fault tolerance and recoverability of the system. By adopting appropriate design and implementation methods, the reliability of the software system can be improved and the occurrence of system failures and errors can be reduced.

5. I) Comprehensiveness of security and reliability measures of network financial software. Network financial software is composed of several functional modules, and there should be corresponding security and reliability measures within each functional module to ensure the legitimacy and correctness of accounting business processing.

6. The six quality characteristics of the software include functionality, reliability, usability, efficiency, stability and portability.Software does not only include computer programs that can run on a computer (a computer here refers to a computer in a broad sense), and documents related to these computer programs are generally considered part of the software.

What is the robustness and robustness of the network?

1. Robustness means strong and strong.It is the ability of the system to survive in abnormal and dangerous situations. For example, whether a computer software can fail or crash in the event of input errors, disk failures, network overloads or intentional attacks is the robustness of the software.

2. High robustness means that the system or network is very strong and stable. Robust is the transliteration of Robust, which means strong and strong. It is also the ability of the system to survive in abnormal and dangerous situations.

3. For example, whether computer software can not crash in the case of input errors, disk failures, network overloads or intentional attacks is the robustness of the software. The so-called "roustness" refers to the characteristics of the control system maintaining certain performance under the perturbation of certain (structure, size) parameters.

4. Robust is the transliteration of Robust, which means strong and strong.It is the ability of the system to survive in abnormal and dangerous situations. For example, whether a computer software can fail or crash in the event of input errors, disk failures, network overloads or intentional attacks is the robustness of the software.

5. Robust is the transliteration of Robust, which means strong and strong. It is the key to the survival of the system in abnormal and dangerous situations. For example, whether a computer software can fail or crash in the event of input errors, disk failures, network overloads or intentional attacks is the robustness of the software.

In the following description of embedded security key system design and system robustness, the error is...

A security-critical system refers to a computer system whose incorrect function or failure will lead to serious consequences such as casualties and property losses.

Most embedded processors have built-in clock signal generators, so the clock circuit only needs an external quartz crystal oscillator and two capacitors to work, but some occasions (such as to reduce power consumption, strict synchronization, etc.) require the use of external oscillation sources to provide clock signals. The description of item B is wrong, so choose B for this question.

[Answer]: D Embedded systems, like general-purpose computers, also consist of two parts: hardware and software. They involve a wide range of fields, far exceeding various types of general-purpose computer systems in terms of applications.

[Answer]: C embeddingThe system is composed of an embedded hardware system and an embedded software system, and the embedded hardware system is composed of an embedded processor, memory, 1/O interface, etc. From the perspective of system operation, embedded hardware systems can be divided into embedded minimum hardware systems and typical embedded hardware systems.

[Answer]: C The embedded system, like a general computer, also consists of two parts: hardware and software. The main body of the hardware is the CPU and memory, which connect with the outside world through I/O interfaces and I/O devices. At present, 8-bit and 16-bit CPUs are the most used in embedded systems, but 32-bit is the mainstream of technological development.

Why is the distributed system robust?

1. Because the processing and control functions of the distributed system are distributed, the failure of any site will not have much impact on the whole system. In addition, when the equipment in the system fails, the system can be reconstructed through fault tolerance technology to ensure the normal operation of the system. All of this shows that the distributed system is robust.

2. The computers in the network themselves are reciprocal, and there is no master-slave division. However, in order to consider its own robustness and reliability, the distributed system will design some redundancy to solve some inevitability of the distributed system itself.

3. This automatic recovery function reflects the robustness of the system. The fundamental starting point and purpose of developing a distributed system is that it has multi-machine cooperation and robustness. It is precisely because of multi-machine cooperation that the system has the characteristics of short response time, large throughput, good usability and high reliability.

4. Strongness. Distributed operating systems have good usability and reliability due to the distribution of processing and control functions, that is, robustness. Due to the centralized characteristics of control functions, the network operating system has a weak system reconstruction function and potential unreliability.

Why the distribution system is robust

Because the processing and control functions of the distributed system are distributed, the failure of any site will not have much impact on the whole system. In addition, when the equipment in the system fails, the system can be reconstructed through fault tolerance technology to ensure the normal operation of the system. All of this shows that the distributed system is robust.

The calculation in the networkThe computer itself is reciprocal, and there is no master-slave division. However, in order to consider its own robustness and reliability, the distributed system will design some redundancy to solve some of the inevitability of the distributed system itself.

The concept of centralized control is not emphasized in the distributed database system. It has a hierarchical control structure based on the global database administrator, but each local database administrator has a high degree of autonomy.
